Optical spectroscopy measurements rely on sources that generate a beam of light with an efficient and stable output. With that in mind, Sarspec offers a number of compact and modular sources for illumination and excitation that can be perfectly combined with each of our spectrometers. Light sources for illumination purposes enable absorbance, transmittance, and reflectance measurements over wavelengths ranging from deep-UV to near-IR. Light sources for excitation purposes generate high-power outputs at specific wavelengths for fluorescence and phosphorescence measurements.
Standard Cuvette Holder
Standard cuvette holder is the ideal accessory for cuvette-based absorbance and high-emissive fluorescence measurements. With an operational range from 190 to 2500 nm, standard cuvette holder includes two 6 mm collimating lenses with SMA 905 connectors and adjustable focus to maximize light throughput.
Multipurpose cuvette holder is the perfect accessory for cuvette-based low-light level fluorescence measurements. With an operational range from 190 to 2500 nm, multipurpose cuvette holder includes two 12.7 mm collimating lenses with SMA 905 connectors and adjustable focus and offers the possibility of adding SiO2 coated aluminium mirrors to enhance the excitation and fluorescence signal.
Q-Pod cuvette holder is a Peltier-controlled support with magnetic stirring for temperature controlled absorbance and fluorescence measurements. A fused silica lens system with SMA 905 connectors provides wide connectivity to optical fibers while the temperature is controlled via Bluetooth wireless or USB cable. Q-Pod allows the temperature to be set between -35°C and +110°C with an accuracy of 0.05°C.
